标题： Direct manipulation of wave amplitude and phase through inverse design of isotropic media

摘要： 在本文中，我们提出了一种新的设计方法，使我们能够从圆柱形入射波中控制电磁波的幅度和相位。 这导致了各向同性材料，并不依赖于变换光学或其准共形近似。 我们的方法得出二维各向同性、非均匀的介电常数和磁导率分布，由此产生一类无散射的波解。 我们的设计基于将复波解分离为幅度和相位。 我们给出了两种类型的例子来验证我们的方法。 显示英文摘要

摘要： In this article we propose a new design methodology allowing us to control both ampli- tude and phase of electromagnetic waves from a cylindrical incident wave. This results in isotropic materials and does not resort to transformation optics or its quasi-conformal approximations. Our method leads to two-dimensional isotropic, inhomogeneous material profiles of permittivity and permeability, to which a general class of scattering-free wave solutions arise. Our design is based on the separation of the complex wave solution into amplitude and phase. We give two types of examples to validate our methodology.
